Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi 

Pull SCSI fixes from James Bottomley:
 "A bunch of fixes for aacraid, a set of coherency fixes that only
  affect non-coherent platforms and one coccinelle detected null check
  after use"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: libsas: align sata_device's rps_resp on a cacheline
  scsi: use dma_get_cache_alignment() as minimum DMA alignment
  scsi: dma-mapping: always provide dma_get_cache_alignment
  scsi: ufs: ufshcd: fix potential NULL pointer dereference in ufshcd_config_vreg
  scsi: aacraid: Prevent crash in case of free interrupt during scsi EH path
  scsi: aacraid: Perform initialization reset only once
  scsi: aacraid: Check for PCI state of device in a generic way
